ford pwm iac & msd question

[gump]

I am running a ford pwm idle air valve [two wire] with a ms2 3.57.Do I hook this up using the fast idle wire? Do I still pull the relay and jumper it?Do I ground the other wire from the idle valve? Also I am using an msd 6al2 with their magnetic pickup [8555-1] distributor and I am not using ms2 to control timing[for now]where do I get the tach signal from for pin 24?The white wire from the msd? thanks in advance

I am running a ford pwm idle air valve [two wire] with a ms2 3.57.Do I hook this up using the fast idle wire?

Yes, the V3.57 can drive a PWM IAC valve directly.

Do I still pull the relay and jumper it?

Yes.

Do I ground the other wire from the idle valve?

No, this should get 12 volt power.

Also I am using an msd 6al2 with their magnetic pickup [8555-1] distributor and I am not using ms2 to control timing[for now]where do I get the tach signal from for pin 24?The white wire from the msd? thanks in advance

Use the tach output terminal from the MSD box.

Thanks Matt,so I can jumper off of my tachometer wire coming from the msd to get a signal. In other words I can use that terminal for both the tach and the megasquirt signal.So does the fidle wire from the realy board control the grounding of the pwm iac?

This generally works pretty well.

Yes. You have to jumper the IAC relay when using the relay board.

Thanks Matt,I will post my project in msruns tonite.
